Air Valve
DN50-800, PN10-40

Working pressure: 1.0-4.0Mpa

Medium: clean water, raw water, municipal sewage water

Operating temperature: normal temperature

main features

When the medium in operation, the valve float stops underneath the seat for a large amount of air venting, when the air is vented, the medium enters the valve, the float raises to seat, the valve will be closed, and the venting is stopped. The pipeline will naturally produce a small amount of air during operation, and these air will gather in the upper part of the pipe, to a certain amount, the water level in the valve will fall, the float will fall along the water and leave seat. The air will be discharged from the small hole

Usually the size of the air valve is the main pipe is from one-twelf to one-six of the size of main pipe

The air valve is easy to leakage when the medium pressure in pipe is too low. A valve must be prepared for maintenance
